CLARINT.

SPECIFICATION forming part of Letters Patent No. 729,309,'da.td. May 26, 1903.

Application led December 30, 1902. Serial No. 137,172. (No model.)

' To @ZZ whom it may concern-.-

Beit known that I, PAULEVETTE, engineer, a citizen of the French Republic, residing at Paris, France, (and having post-office address 18 and 20 Passage du Grand Cerf, in said city,) have invented certain new and useful Improvements in Clarinets, of which the following is a specification.

This invention has for its object an improvement in clarinets, permitting to act on the keys for trilling the keys A-natural and the key G-sharp with the forefinger of the right hand.

In order that this invention may be clearly understood, I shall describe it With reference to the accompanying drawings, .of which- Figure l is a view of a part of a clarinet of `the Boehms system, for instance, having the said improvement. Fig. 2 is a partial section of this clarinet, and Fig. 3 is a detail.

In the clarinets of the Boehms system the key A-natural is trilled by opening simultaneously the keys a and b by means of a finger-piece c and the key G-sharp is trilled by opening only the key b by means of a fingerpiece d.

In order to set the keys a and b with the foreiinger of the right hand, I have devised the following dispositions: The simple heads @fare made double, as shown at e cff. In the heads ef a rod g is mounted loose and rotates in these bearings c f. This rod gis provided at its upper end with an arm h and at its lower end with a bent lever ended by a finger-piece t'. Concentrically to the rod g and somewhat shorter is a hollow rod j, rotating on the rod g and provided at its upper end with an arm 7a and at its lower end with a bent lever ended-by a nger-piece m. The finger-piece c is provided with a projection fn, on which bears the end of the arm 7o. A short arm o is fitted to the rod of the4 key b and is, in connection with the lever p, pivotally mounted on q, the arm 7L bearing on the other arm of the said lever p.

In order to act on the keys for trilling the A-natural with the foreiinger of the right hand, the operator acts with the said foreinger on the finger-piece m. The hollow rod j rotates around the rod g. The arm k bears on the projection n of the nger-piece c and presses the said finger-piece c, trilling simultaneously the key a and the key b.

In order to act on the key G-sharp with the foreflnger of the right hand, the operator acts on the finger-piece t', and' thus the rod gis rotated in the hollow rod j, the arm h bearing on the lever p, which oscillatesV on its pivot 'q and raises the short arm o, thus trilling the key G-sharp.

It is well understood that the linger-pieces may have different forms and dispositions.

This disposition may be used for other clarinets than those of Boehms system. For instance, it may be used on the clarinets with thirteen keys.

Having now particularly described my invention and in what manner the same may be performed, I declare that what I claim is l. In a clarinet'an improvement for acting on the key G-sharp with the forenger of the Y right hand, consisting in a rod g, two heads e f in which the said rod rotates, a ingerpiece t' provided at the lower end of the said rod, an arm h provided at the upper end of the said rod, a lever p brought in action by the said arm h and an arm o fitted on the rod of the key G11 in connection with the said lever p, substantially as described.

2E In aclarinet an improvement for acting on key Gsharp and the key A-natural with the foreinger of the right hand, consisting in a rod g, two heads c f in which the said rod rotates, a nger-piece e' provided at the lower end of the said rod, an arm h provided at the upper endof the said rod, a leverp brought in action by the said arm 71, and an arm o fitted on the rod of the key G in connection with the said lever p, a hollow rod j concentrically surrounding the rod g, a finger-piece 'm at the lower end of the said rod y', an arm la at the upper end ofthe said rod j, a projection n of the finger-piece c in connection with the saidV arm 7c, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing Wit- DQSSSS.
